SATNOEIS was a River-God of the Troad, in Mysia, Anatolia (modern Turkey).

The River Satnioeis had its headwaters near the peak of Mount Ida. It flowed west, issuing into the Aegean Sea between the towns of Khryse and Hamaxitos in the South-Westernmost corner of the Troad. Neighbouring rivers were the Skamandros to the north, and Kaikos to the south-east.
